My invention relates to improvements in faucets. 4 Y

In accordance with myinvention, I provide a faucet formed of few andsimple parts,

and. which may be conveniently and quickly operated and is reliable inuse. The faucet 1s so designed that it has a large water waytherethrough so that it will deliver a large quantity of water quicklywhich is lmpor- 0. tant in drawing water for bath tubs, kitchen sinks,sinks -in industrial plants, etc. The faucet is so constructed that thevalve element closes with the pressure of the water, and the valveelement and valve seat are ground at an angle of substantially 45degrees insuring a perfect fit, and eliminating the possibility ofleakage, due to the accumulation of deposits, rust, etc. The faucet isadapted to be used on high pressure work. so The faucet is soconstructed that the valve element engages a 'stationary non-removablevalve seat, and the valve element and valve stem are removable from thebottom of the casing of the faucet, the valve element belng removablefrom the valve stem and reversible so that its opposite faces may beused. The valve stem has screw-threads of relatively high pitch, so thatthe valve element may be opened and closed by a turning movement of thehandle of the faucet for about a quarter to a half of a revolution.

In the drawings, wherein for the purpose of illustration, is shown apreferred embodiment of my invention, the numeral 5 designates thecasing of the faucet, which is provided at its forward end with a spoutor 5- nozzle 6, and at its rear end witha tubular portion 7, forsuitable connection with a pipe. The casing 5 carries an upstanding neck8. The casing 5 is providedwith a diagonal web 9, forming-inlet andoutlet chambers 10 and 11. This web carries an upstanding annular ringor flange 12, integral therewith, as shown. The web 9 has a circularopening 13, leading into the flange 12, and a valve seat 14 is groundupon the web and surrounds the opening 13. The valve seat 14; is annularand is inclined at an angle of 45 degrees from the vertical. The valveseat is, therefore, stationary and is integral with the web.

The numeral 15 designates a valve stem cage, the lower end of which isinserted within the flange 12, and has screw-threaded engagementtherewith, as shown at 16. This cage has relatively large openings 17,in its periphery, for the free passage of the water, the cage beingtubular with its lower end open, as shown. Formed integral with theupper end of the cage 15 is a sleeve 18, provided at its top with anannular disc or flange 19, having a sliding fit within the upstandingneck 8. This disc has notches 20, formed in its periphery for engagementwith a spanner wrench or like implement, to turn the same.

The flange or disc 19 is spaced from the upper end of the neck 8,affording a space for a compressible coil spring 21, engaging a metalwasher 22, in turn engaging a flexible or fibrous washer 23, held withina cap 24, having screw-threaded engagement with the upper end of theneck 8. as shown at 25.

The numeral 26 designates a valve stem, extending through an opening 27in the cap, and having screw-threads-QS formed thereon to engagescrew-threads 29 in the sleeve 18. The valve stem embodies a reducedportion 30 extending through the cage 15, and this reduced portion isequipped with a shoulder 31 and an extension beneath the shoulder, theseparts being'formed integral. The extension 32 projects below the valveseat 14 and receives thereon an annular valve element 33, engaging awasher 34, held in place by a nut 35 having screw-threaded engagementwith the extension 32, as shown at 36. The periphery of the valveelement 33 has oppositely arranged beveled faces 37, disposed at anangle of 45 degrees from the vertical. The valve element is readilyremovable from the extension 32, so that either face 37 may be arrangedadjacent to the valve seat 14 for co-action therewith. The casing 5 isprovided in its bottom with a main opening 37 in alignment with thevalve element 33, so that this valve element may be moved downwardlythrough this opening, and the opening is covered by a removable plug 38.The valve stem 26 is turned by means of a radial handle 39, detachablysecured to the stem 26 by a screw 40, or the like. In assembling theseveral parts of the faucet, the cap 24 being removed, the cage 15 isinserted downwardly through the neck 8 and its lower end engages withinthe flange 12 and is screwed up tightly within the same. The plug 38being removed, the valve stem 26 is inserted upwardly through theopening 37', until its screw-threaded portion engages Within thescrew-threaded sleeve 18, the stem 26 being then rotated until the valveelement 35 engages the valve seat 14. The lug 38 may then be screwedinto the openmg 37 It is obvious that the stem 30 may be readil removedso that the valve element 33 may e reversed thereon, and the parts againassembled. The spring 21 and washer 22 are now inserted into the upperportion of the neck 8 above the flange 19 and the cap 24 placed upon thevalve stem 26 and screwed upon the top of the neck 8. The handle 39 isnow attached to the top of the stem 26. The screw-threads 28 and 29 havea relatively high pitch, and the valve element 33 may be opened andclosed, by turning the handle 39 for a quarter to a half of arevolution. The handle 39 is turned to the left to unseat the valveelement, and to the right to seat it.

In Figures 5 and 6, I have shown a modifled form of valve element. Thisvalve element is designated, as a whole, by the numeral 41, and includesan inserted cup-shaped portion 42, secured to an inner tubular portion43, spaced therefrom to afford a passage 44. The tubular portion 43 ismounted upon the stem 30, beneath the flange 37, and is held in place bythe nut 35. The cup-shaped portion 42 engages the valve seat 14, and thewater under pressure enters the cup-shaped ortion 42, expanding the sameand forcing it against the valve seat 14.

It is to be understood that the forms of my invention, herewith shownand described, are to be taken as preferred examples of the same, andthat various changes in the sh p size and arrangement of parts ma beresorted to, without departing from t e spirit of m invention, or thescope of the subjoine claims.
